Reynold Number given Settling Velocity of Spherical Particle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Reynolds Number = (Settling Velocity*Diameter)/Kinematic Viscosity
Re = (v_s*D)/ν
This formula uses 4 Variables

Variables Used

Reynolds Number - The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.
Settling Velocity - (Measured in Meter per Second) - Settling velocity is defined as the terminal velocity of a particle in still fluid.
Diameter - (Measured in Meter) - Diameter is a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
Kinematic Viscosity - (Measured in Square Meter per Second) - The kinematic Viscosity is an atmospheric variable defined as the ratio between the dynamic viscosity μ and the density ρ of the fluid.

STEP 1: Convert Input(s) to Base Unit

Settling Velocity: 1.5 Meter per Second --> 1.5 Meter per Second No Conversion Required
Diameter: 10 Meter --> 10 Meter No Conversion Required
Kinematic Viscosity: 7.25 Stokes --> 0.000725 Square Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Re = (v_s*D)/ν --> (1.5*10)/0.000725

Evaluating ... ...

Re = 20689.6551724138

STEP 3: Convert Result to Output's Unit

20689.6551724138 --> No Conversion Required

FINAL ANSWER

20689.6551724138 ≈ 20689.66 <-- Reynolds Number
